In CodeIgniter, how is code coverage used in the context of unit testing?
- Code coverage calculates the time taken to execute unit tests.
- Code coverage determines the number of comments in the code.
- Code coverage is used to track the number of lines in the code.
- Code coverage measures the percentage of code that is executed during the unit tests.
Code coverage in CodeIgniter's unit testing context is a metric that indicates the percentage of code executed during the tests. It helps developers identify areas of the codebase that are not covered by tests, allowing them to create additional tests for better overall coverage. High code coverage is desirable as it indicates that most parts of the code have been tested, reducing the likelihood of undetected bugs in untested areas.
How does CodeIgniter's logging mechanism assist in identifying security issues?
- Captures and logs security-related events
- Logs only fatal errors
- Provides a detailed performance report
- Records user login information
CodeIgniter's logging mechanism helps identify security issues by capturing and logging security-related events, aiding in detecting and analyzing potential security threats.
The ________ method in CodeIgniter 4 Models allows for custom query building.
- build()
- custom()
- execute()
- query()
In CodeIgniter 4 Models, the query() method is used to execute custom SQL queries. This method allows for flexible and manual construction of queries when the standard query builder is not sufficient.
What is the primary function of database helpers in CodeIgniter?
- Database helpers are used for loading database sessions.
- Database helpers assist in creating and managing database connections.
- Database helpers help with debugging and profiling database queries.
- Database helpers provide authentication mechanisms for database access.
CodeIgniter's database helpers primarily assist in creating and managing database connections. They simplify tasks related to database interaction in CodeIgniter, such as connecting to the database and executing queries.
For advanced XML processing, CodeIgniter can be integrated with the PHP extension _______________.
- DOMDocument
- SimpleXML
- XMLReader
- XMLWriter
CodeIgniter can be integrated with the PHP extension XMLReader for advanced XML processing. XMLReader provides a stream-oriented XML parser, allowing efficient processing of large XML documents.
The ________ method in CodeIgniter is used for adding default data during seeding.
- $this->db->insert()
- $this->db->insert_batch()
- $this->db->populate()
- $this->db->seed()
In CodeIgniter, the $this->db->seed() method is used for adding default data during seeding.
Which file in CodeIgniter is typically modified to include a third-party library?
- autoload.php
- config.php
- index.php
- routes.php
The autoload.php file in CodeIgniter is typically modified to include a third-party library. This file contains the configuration for auto-loading various resources, including libraries. Adding a third-party library to the autoload configuration ensures that it is loaded automatically when the application starts, making it readily available for use throughout the code.
In CodeIgniter, where are session data typically stored by default?
- Cookies
- Database
- Server-side files
- URL parameters
By default, CodeIgniter stores session data on the server-side in files. This provides a secure and efficient way to manage user sessions without exposing sensitive information in cookies or other less secure methods.
The technique of _________ effectively limits SQL injection by stripping out SQL commands from user inputs.
- Code Obfuscation
- Data Encryption
- Input Sanitization
- Output Validation
Input Sanitization is a security technique that involves cleansing user inputs to remove potentially harmful content, such as SQL commands. This helps prevent SQL injection attacks by ensuring that only valid and safe data is processed.
In CodeIgniter, to perform a database insert operation, the Model method used is ________.
- add()
- create()
- insert()
- save()
The correct method for performing a database insert operation in CodeIgniter is insert(). This method is used to insert data into the database table. It is essential for creating new records.
